From now on, we don't allow jailed processes to open all device nodes in /dev, but only allow jailed processes to open /dev/full, /dev/zero, /dev/null, and various TTY and PTY devices (and not including virtual consoles) so we basically restrict applications to what they can do when they are in jail. The motivation for this type of restriction is to ensure that even if a remote code execution occurred, the damage that can be done is very small. We also don't restrict reading and writing on device nodes that were already opened, because that limit seems not useful, especially in the case where we do want to provide an OpenFileDescription to such device but nothing further than that. |
